So far, I have done similar things to you, but also cut some PTFE rings for the ends of the spring from some 0.5mm sheet off the 'bay.
I am keeping the leather seal as it is in pretty good condition, apart from being a bit dry - currently soaking in some SAE30 oil.
All the trigger contact points are now polished, I just need to clean out the main tube. I too am curious about the transfer port, what effect reducing it has, and how on earth to acomplish it down the end of a narrow tube!

Cheers,

Nice! What type of Mk3 have you got? I'd love to feel the difference between 1st, 2nd and 3rd type triggers. Apparently the 2nd type are best (although nobody seems to like any of the Mk3 triggers very much...).

Btw one explanation of my low power issues could be the pellets I'm using. Should have known that this old barrel needs 5.6 mm or at least 5.55 mm pellets. Will have to find some.
